Why Do We Have to Wear Sunscreen
UVB rays, which penetrate the outermost layer of our skin, can cause sunburns, skin cancer, and premature skin aging. Sunscreen is an effective way to protect our skin from the harmful effects of UVB rays, with physical and chemical blockers being the two types available. It is important to choose a broad-spectrum sunscreen with an SPF of at least 30 and water-resistant properties, and to also use other sun protection methods such as wearing UPF clothing and avoiding sun exposure during peak hours.
